Transducer Electronic Data Sheets: Anywhere, Anytime, Anyway

Abstract

Transducer electronic data sheets (TEDS) are a key element of smart transducers because they support core features such as plug and play, self-calibration, and self-diagnostics. The ISO/IEC/IEEE 21451-4 standard defines templates to describe the most common types of transducers and suggests the use of one-wire memories to store the corresponding data. In this paper we explore new ways to store and access TEDS tables, including near field communication (NFC) tags and QR codes. We also present a mobile TEDS parser, compatible with Android, that is capable of reading TEDS data from all supported mediums (one-wire memories, NFC tags, and QR codes) and decoding them as human-readable text. The idea is to make TEDS available in the easiest way possible. We also underline the need to extend the 21451-4 standard by adding support for frequency–time sensors. A new TEDS template is proposed, and filling examples are presented. The main novelties of the paper are (i) the proposal of new ways to store 21451-4 TEDS tables using NFC tags and QR codes; (ii) the release of new tools to access TEDS tables including a mobile parser; and (iii) the definition of a new TEDS template for frequency–time sensors.

Smart Sensor Management System Supporting Service Plug-In in MQTT-Based IIoT Applications

“…[13] presents the development result of managing the RFID sensor system through a virtual TEDS data editing tool that supports RFID sensor data management. [6] introduces an approach that turns non-TEDS sensor devices into plugand-play smart sensors. This work also introduces the development method of a writer tool that stores the virtual TEDS created using a commercial virtual TEDS editing tool as binary TEDS data in the EEPROM of the sensor device, and a mobile parser that converts the binary TEDS data into programmable data.…”

“…After interfacing this EEPROM between IoT devices and legacy sensors, TEDS data is written to the EEPROM via software programming. Through the connection between PC and IoT devices, TEDS data can be written in EEPROM using open source OneWire library [5]-based programming [6]. Another way to create TEDS sensors using legacy sensors is to use software that supports DAQ and TEDS data editing, such as LABVIEW of National Instrument.…”

Emerging Wireless Sensor Networks and Internet of Things Technologies—Foundations of Smart Healthcare

“…The functionality of next-generation sensor devices, such as self-organizing and cooperative data processing, greatly enhances the performance of traditional WSNs, especially in specific applications, such as for example, industrial and healthcare IoT applications. In the last 20 years, smart sensor technologies have been the subject of intensive research activities, intending to adopt the necessary standards to support the "plug-and-play" concept, in which sensors from different manufacturers will be compatible and their replacement will be realized in a simple and efficient way [29]. Thanks to the advanced features of the integrated circuit design and packaging process, as well as an affordable cost of implementation, modern electronic systems have become an integral part of IoT sensor networks.…”

Network of Smart Tip-Timing Sensors in Distributed Blade Health Monitoring System

“…Currently, many types of sensors such as pressure transducers, strain gauges, thermometers and accelerometers are available in smart versions, compliant with the IEEE 1451 standard, which defines the communication method and the set of essential data about the sensor known as the transducer electronic data sheet (TEDS). The standard can also be used for frequency-time sensors, which include BTT / BHM sensors [13,14], but it has not been adopted widely. In addition, sensors operating at elevated temperatures [15] are often not smart due to the lack of electronics or its relocation to external conditioning systems.…”
